Injection molding is a manufacturing process for producing different plastic parts by injecting molten material into a mold. The plastic injection and blow molding process are reliable methods to manufacture the best quality products. These are the two most popular ways to obtain high-quality, cost-effective plastic parts and products. However, both have different approaches, techniques, and applications. In these processes, PVC and HDPE molding machines<\/strong><\/em><\/a> are the main manufacturing equipment.\u00a0<\/p>\n

The Difference in Process: Injection Molding and Blow Molding:<\/h2>\n

In the case of injection molding, the injection of melted resin takes place in a hollow mold until it is completely filled. After this, it is important to apply intense pressure to hold the injection mold together for every part of the interior to be filled with high-pressure molten plastic resin. The ton of pressure applied determines the size and the cost of the PVC molding machine.<\/p>\n

With blow molding, you need to heat a plastic tube and fill it with air until it essentially becomes a balloon of hot plastic. You then need to clamp a mold around this, trapping the plastic while air continues to fill the parison into the shape of your part. The weight of the plastic used in the mold determines the size and associated costs.<\/p>\n
